A
properly installed and approved backflow preventer is a
mechanical device that prevents water from reentering the
water main. This can occur if you have a lawn sprinkler
system, boiler or fire protection system that is fed by the
potable water system. If a sudden drop in water pressure
occurs it could cause back siphonage from your lawn
sprinkler system contaminating your drinking water with weed
killer, fertilizer or pesticide that can cause health
problems.
To ensure you are in compliance with your local water
purveyor, backflow preventers must be tested by certified
testers for proper operation upon installation, repair or
replacement and at least yearly thereafter. Call any of our
contractors for a consultation today. |
